COMPANY HEADER
Optical adhesives provide low-stress, low-movement, and gap filling to 1/4 inch for lens bonding, laminating, and positioning, VCSEL potting, optical mounting, and fiber optic assembly applications. One-part optical epoxies cure in seconds to UV/Visible light and bond well to glass, metal, ceramic, quartz, and plastic substrates. High-tensile-strength, optically clear bonds of 3,000 psi, and shrinkage as low as 0.1% are possible.

  • Rapid UV/Visible light cure
  • Excellent light transmission properties
  • Low stress, shrinkage, and outgassing properties result in low movement
  • One component and no mixing
  • Optically clear formulations

Additional Information N/A Optical Adhesive for Bonding Plastics to Glass and Metal

Dymax® OP-29 UV cure optical adhesive forms tough, resilient bonds to glass, metals, and a variety of plastics including polycarbonate and polyimide. OP-29 adhesive cures in seconds upon exposure to UV light. OP-29 adhesive is available in two viscosities: a free-flowing liquid (OP-29) or as a thixotropic gel (OP-29-GEL).

Recommended applications included tacking, bonding, sealing, and potting.

Dymax® materials are no solvents added and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax® UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax® lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. 		N/A Multi-Purpose Light-Curable Optical Adhesive

Dymax® OP-29-GEL UV curable optical adhesive forms tough, resilient bonds to glass, metals, and a variety of plastics including polycarbonate and polyimide. OP-29-GEL adhesive cures in seconds upon exposure to UV light.

Dymax® Low-Shrink™ OP-81-LS is a UV/Visible light-curable optical adhesive epoxy with very low shrinkage during cure and is ideal for rapid positioning of optical components. OP-81-LS cures with UV light and includes a low-temperature heat-curing function in applications where shadow areas exist or where heat cure only is preferred. This one-component optical epoxy is recommended for surfaces and substrates including polycarbonate, glass, acrylic and metallic surfaces.

OP-81-LS requires cold storage/cold shipping and should be kept between 1 ºC (34 ºF) and 5 ºC (41 ºF) in the original, unopened container.

Dymax® materials contain no nonreactive solvents and cure upon exposure to light. Their ability to cure in seconds enables faster processing, greater output, and lower processing costs.
